after 4 hours of searching for answers and trying everything I could I need specific help. I write a report and I want to include a bibliography. I still get these error messages:

  1. Empty bibliography
  2. There were undefined references
  3. Please (re)run BibTeX on the file(s):(biblatex) "Filename"(biblatex) and rerun LaTeX afterwards.
  4. Citation 'Example Cite' on page 3 undefined*

My code looks like this:

    \documentclass[12pt, twoside]{report}
%Standard Packages
%\usepackage[round, authoryear]{natbib}

% zusätzliche Schriftzeichen der American Mathematical Society














I also have a part of my bibfile:

@book{Fluid Mechanics Seventh Edition,
    author    = {Frank M. White},
    title     = {Fluid Mechanics, Seventh Edition},
    year      = {2011,
    publisher = {McGraw-Hill}

When I am using Quick Build to file the document: latex + Bibtex + 2x Latex + Viewpdf is executed. What do I have to do to get the bibliography printed? Thanks very much for helping!

   author    = {Frank M. White},
   title     = {Fluid Mechanics, Seventh Edition},
   year      = {2011},
   publisher = {McGraw-Hill}

in your LaTeX source, everything works fine on my box.
